Under-corn seedbed strip-like water supplementing multifunctional seeder

Abstract

An under-corn seedbed strip-like water supplementing multifunctional seeder aims to integrate under-seedbed water supplementation, ridge forming, film covering and fertilization, and a film covering width and a fertilizing amount are adjustable. The under-corn seedbed strip-like water supplementing multifunctional seeder comprises a water tank, a stander, a traction frame, a fertilizing device, a ridge forming device, a water supplementing device, a film covering device, a seeding device and an earth covering device, wherein the stander comprises a centre sill, a front spar and a rear spar; the ridge forming device comprises a sleeve, a ridge forming plate and a fixed piece; the water supplementing device comprises an opener, a vertical pipe, a water duct, the sleeve and an earth covering plate; the fertilizing device comprises a fertilizing box, a chain wheel I, a chain II, a drive chain, a fertilizer discharge shaft I, a fertilizer discharge shaft II, a land wheel, a land wheel shaft, a furrow plough-type opener and a fertilizer delivery pipe; the film covering device comprises a tension rod, a film suspending rod and an iron chain; the film suspending rod is provided with two clamps used for fixing mulching films; the seeding device comprises duck bills, a turntable-type seed cabin and a connecting rod; the earth covering device comprises a disc-type earth coverer and an earth-retaining plate; and the disc-type earth coverer is fixed on the connecting rod of the seeding device.

Description

technical field [0001] The invention relates to a multifunctional seeder which integrates corn ridge formation, film covering, planting water replenishment and fertilization. Background technique [0002] Because plastic film has the functions of increasing temperature, preserving moisture and increasing yield, the cultivation technology of corn plastic film covering has become a conventional planting technology in the arid areas of northern my country and has been widely used, especially in cool and cold areas, and has realized mechanized film-covered sowing. However, under the influence of the continental monsoon climate in our country, there is a phenomenon of "nine spring droughts in ten years" in most parts of the north. Since one of the principles of plastic film mulching is "cover wet but not dry", plastic film mulching cultivation techniques are often used in drought conditions. Sowing cannot be carried out, so a large amount of farmland cannot be sown properly due t...

Problems solved by technology

However, under the influence of the continental monsoon climate in our country, there is a phenomenon of "nine spring droughts in ten years" in most parts of the north. Since one of the principles of plastic film mulching is "cover wet but not dry", plastic film mulching cultivation techniques are often used in drought conditions. It is impossible to sow seeds, so a large amount of farmland cannot be sown properly due to spring drought every year. In severe drought years, large areas of land are abandoned

To cope with the spring drought, the common method used by farmers is to artificially replenish water and sow seeds, such as artificially seated water seeds, which is time-consuming and labor-intensive

Drought not only occurs during the spring sowing season, but also occurs frequently during the crop growth period. In order to cope with the drou
